Journal ArticleDOI
Projected global stability of high beta MAST-U spherical tokamak plasmas
John Berkery,Guoliang Xia,S.A. Sabbagh,J.M. Bialek,Zhirui Wang,C. J. Ham,A.J. Thornton,Yueqiang Liu +7 more
TL;DR: In this article, the MAST-U spherical tokamak experiment was evaluated with the DCON and MARS-F stability codes to find the so-called "no-wall" beta limit, above which resistive wall mode instabilities can be expected in the absence of other stabilising effects.
Journal ArticleDOI
Improved feedback control of wall stabilized kink modes with different plasma–wall couplings and mode rotation
Q. Peng,J.P. Levesque,Chris Stoafer,J.M. Bialek,P.J. Byrne,P.E. Hughes,Michael E. Mauel,Gerald Navratil,Dov Rhodes +8 more
TL;DR: In this article, a feedback control algorithm for rotating, wall-stabilized kink modes in the High Beta Tokamak-Extended Pulse (HBT-EP) device maintains an accurate phase shift between the perturbation and the measured rotating mode through current control, with control power emphasizing fast rotation and phase jumps over fast amplitude changes.
